+* 4.4.0 (December 3, 2016)
+
+ New features:
+ - Add configure support for *-*-linux-android. (@cferris1000, @jasone)
+ - Add the --disable-syscall configure option, for use on systems that place
+ security-motivated limitations on syscall(2). (@jasone)
+ - Add support for Debian GNU/kFreeBSD. (@thesam)
+
+ Optimizations:
+ - Add extent serial numbers and use them where appropriate as a sort key that
+ is higher priority than address, so that the allocation policy prefers older
+ extents. This tends to improve locality (decrease fragmentation) when
+ memory grows downward. (@jasone)
+ - Refactor madvise(2) configuration so that MADV_FREE is detected and utilized
+ on Linux 4.5 and newer. (@jasone)
+ - Mark partially purged arena chunks as non-huge-page. This improves
+ interaction with Linux's transparent huge page functionality. (@jasone)
+
+ Bug fixes:
+ - Fix size class computations for edge conditions involving extremely large
+ allocations. This regression was first released in 4.0.0. (@jasone,
+ @ingvarha)
+ - Remove overly restrictive assertions related to the cactive statistic. This
+ regression was first released in 4.1.0. (@jasone)
+ - Implement a more reliable detection scheme for os_unfair_lock on macOS.
